What you've heard is true. Once you drive a BMW, you will be hooked for life. I love driving the X3, so does my husband. His Acura MDX now gets very little action. He prefers the X3. Lots of power. Handles beautifully on Seattle's wet roads and in heavy traffic. Nice size to parallel park downtown.
The X3 is very responsive. The panoramic sunroof is as close as you can get to a convertible in an SUV. Heated rear seats are a favorite, too.
All minor. The auxiliary input for the iPod is located in the back of the center arm rest, where it is not convenient for the driver and looks odd to passengers in the back. Also no place to store sunglasses and only one cup holder in the center. (The passenger holder is by the passenger door.)
